Am I wrong for this?

I am almost 13 weeks pregnant. My boyfriend recently got me an engagement ring and we live together. I am starting to get more energy back and I'm able to go to more events with him and spend more quality time with him like he wants. Today we went to a baseball game and I drove him there and back so he could drink. We get back from the game for 5 minutes and he leaves to go to the bar to meet a friend. He stays out from 7pm-3am. I text him asking where he is because the bar is closed. Then he comes home and sleeps on the couch. No explanation, no text back, nothing. Am I wrong for being upset about this? He acts like it's no big deal. I told him when he drinks we always argue. He said he will stop drinking, but then stays out for 8 hours. I feel like he isn't happy with me or that he isn't ready for commitment and a family. It makes me really upset.
